The trailer features new mommy and CIA operative Carrie Mathison (Claire Danes) as she struggles with a new set of conflicts that arise with her recently appointed position in the Middle East. It also features some familiar faces (Mandy Patinkin and Rupert Friend) and some newbies too, including Corey Stoll ("House of Cards") and Suraj Sharma ("Life of Pi"). 

Season 4 of "Homeland" will premiere on Showtime on October 5. Until then, check out the trailer below.
